Is there a way to find out which table is stored on which datafile?
Considering more than one datafile in each filegroup.

If the data files are all in the same file group, then no. Data could be spread among several data files.

Objects can't cross filegroups, but if you have multiple files in your filegroup, it would be on more than one.

You can find what filegroup the table is in by querying sys.partitions and sys.data_spaces.
If a table is on a filegroup with multiple files it'll be striped across all the files (unless the files were added after the last change to the table's data)

Thank you all for quick response.
If I have added a new file in filegroup, new rows added to a table will again striped across al the files, right?
